Neotypes are designated for nine species, including the type species O. foveatus Kieffer, Oxyscelio brevinervis (Kieffer), Oxyscelio bifurcatus (Kieffer), Oxyscelio frontalis (Kieffer), Oxyscelio crassicornis (Kieffer), Oxyscelio cupularis (Kieffer), Oxyscelio foveatus Kieffer, Oxyscelio kiefferi Dodd, Oxyscelio magnus (Kieffer) and Oxyscelio marginalis (Kieffer). Oxyscelio bifurcatus (Kieffer) syn. n. and Oxyscelio frontalis (Kieffer) syn. n. are synonymized under Oxyscelio consobrinus (Kieffer). The fauna is divided into 13 species groups, with six species unplaced to a group. A phylogenetic analysis employing 73 morphological characters did not find most of these groups to be monophyletic, but they are retained to aid in specimen identification. Potential biogeographical patterns are discussed, including regional variation in surface sculpture and a morphological link between Sri Lankan and Australian species.
